http://maccss.ncdpi.wikispaces.net/home This link provides updated versions of the old “Week by Week” documents from the NC Department of Public Instruction. The lessons are now aligned with the Common Core and the eight Math Practices. The link takes you to the Math Wiki. On the left, click on Elementary or Middle, and then go to a specific grade. Look for “Lessons for Learning”.

http://thinkingblocks.com/ Thinking Blocks is a suite of learning tools designed to help students solve math word problems accurately and efficiently. Using brightly colored blocks, students model mathematical relationships and identify known and unknown quantities. The model provides students with a powerful image that organizes information and simplifies the problem solving process. By modeling increasingly complex word problems, students develop strong reasoning skills which will facilitate the transition from arithmetic to algebra.

http://learnzillion.com/-There are videos that go along with each standard. You can set up your own account or use your Google (gmail) account. You could use these to flip the classroom or let the students use the videos as review. Best of all, it’s free.

http://www.ixl.com/standards/common-core/math Online question bank aligned with the Common Core standards broken down by grade level and then topic. If students get the problem wrong, the computer offers an explanation. There are a limited number of questions you can do for free.

http://www.nctm.org/resources/content.aspx?id=32702 NCTM offers a free interactive software tools for algebra and functions, geometry and trigonometry, and statistics and probability. The tools are appropriate for use with any high school mathematics curriculum and compatible with the Common Core State Standards for Mathematics in terms of content and mathematical practices. Java required. Choose “downloadable suite”.

http://www.geogebratube.org/ A resource where students can create their own drawings like geometer sketchpad but there are also archived pages where other teachers have made their own drawings. For example you can find a drawing proof for the Exterior Angle Theorem.

http://www.illustrativemathematics.org/ Illustrative Mathematics provides guidance to states, assessment consortia, testing companies, and curriculum developers by illustrating the range and types of mathematical work that students experience in a faithful implementation of the Common Core State Standards, and by publishing other tools that support implementation of the standards.
